To A@ZZ whom it may concierne.-

-Beit known` that I,"SAMUEL J. PARKER,

Mof Ithaca, Tompkins county, N ew York, have invented certain Improvements in Fruit-Jars;

and I do hereby.V declare that the following is a fullv and exact description thereof, reference being had to the accompanying drawings,vand

:to the letters of reference marked thereon.

The drawings will be explained in detail,

make a jar very 'snug and close mouthed es-v pecially adapted to transportation and packages for sale,'a nd bythese forms meet the varied'demands ofthe public wants.

The first object I accomplish by using the stopper intentionally made as simple as ,possible, as j ust described; `but I make a deiiee-A tion inthe sides of theneek of the jar above the shoulder, so that as the rubber ring is pressed through the construction the stopper 'with its ring snaps into its place, similar to the devices used in tobacco-boxes and spectacle-cases, and other similar articles, only that in these objects the elasticity ofy the metal or other material of the box or case makes the snap; but in my fruit-jar the inelastic neck of the jar and inelastic stopper fit or automatically close by a snap caused bythe elasticity of the ring. 4The adjustment must beso made that while the ring gives away before the con.- striction, it shall yet be air-tight when under the lesser pressure of the enlarged space be' .lowy the constriction. A little practice in manufacture soon enables one to do this. Thus Ihave a very simple and effective retention Mysecond object is best secured by making the jar of stoneware', yet I use glass or earthen ware, and the device is useful for other fruits besides vegeta-blc fruits. In this ease I makev mystopper of granulated cork, preferring the commercial article called cork-wood. This I agglutenize by india-rubber, or shape into a center by any means, and over it I put a coa-ting or shell of india-rubber. I- also make the edges thicker for greater elasticitvyand insert auwire for a withdrawing-ring; `or I make ,the same result in parts clamped together by .screws or held by solder. Thus I make an airtight stopper elastic and easily;r adjustable.

- My third object I accomplish'. by makiig a neck rising bylanl inward inclination above' the `iar, and with a close-fitting outside' glass cap; and in thcspace between them I put a:

-thin but broad belt of rubber, and to retain the cover in placel I corrugat-e or roughen the| outside ofthe neekand the inside of the sides of the cover. This makes a compact and retent-ive closure, ,well adapted to transportat-ion. To facilitate the removal of the capcover, I cast the outside of the cap in diamond roughness. vThus I make this form of my jar. This is appa-rent in the drawings, where- L Fig. Ill is la sectional View of the Snap forni of my jar. In it a, is the stopper, and b b the india-rubber ring,whichis made as represented, or lin similar forms. The constriction o o is seen, and in it lies the rubber ring, in the space a1 below the constriction;4 and c is a glass knob, into which an iron ring, d, is thrust, which is to draw the vstopper out by.

Fig. 2 is the stopper with? air-inclined or cani'surface, so that in closing the. air passes out from j' a toy'.

Fig. tis atop view ot' the stopper seen in Figs. l, 2, and 3, showing that the rubber ring extend? outside of the stoi'iper-lip, but is not compre. sed by it. A

Fig. 5 is a. sectional View of my granulatedcork and cork stopper. b b are the thicker portions of the rubber shell, and c eth'e thinner parts.- A' bent wire, ff, holds the extracting ring d. Irig. 5, at M, shows a common cork, or a granulated cork, covered by a rubberclotheapsule, or stretched-rubber capsule, and' clamped about the core bythe disks m. and n, by the rods through it, one of which holds the ring-handle 4by which the stopper is extracted.

1 a Fig. o, at .fr a, shows an angular form of the snap constriction, (seen inITig. 1,) and :r b a rounded form of the sa1ne. Other variations might be shown. Fig. '7 ismy jar-for transportation. y In it g g y is the cap-cover, and o Z. the rubber ring between the corrugated or otherwise ro'ughened inside of the cap and outside of the neck A1' The sides of the outside of the `cap o u and y 7 are cut in diamondv striction above the ring, that the sl Oppcr Shall Snap or antomaticnily clse, und be retained by the constriction as the 'im' closed, :is described.
